(crm-1) This invention relates to a motor vehicle radiator cleaner and tester, and has for the primary object the provision of a device of this character which is easy and quick to operate and is so con- 5 structed that a' cleaning fluid under a selected'l parts to be hereinafter more'fully described and claimed. l5 For a complete understanding of my invention, reference is to,be.had to the following description and accompanying drawing, in which The ngure is a side elevation illustrating a radiator cleaner and leak checker constructed in 20 accordance with my invention.

' Referring in detail to the drawing, the characters A and B designate companion tanks suitably supported and equipped with a drainmedium I including in its construction control valves 2 whereby either or both of said tanks may be emptied of their contents. Sight gages l are provided for the tanks and are located adjacent'the upper ends thereof so that a person may readily -deter'mine when said tanks contain la proper amount of fluid. The tanks contain a suitable cleaning fluid.

Secured to and depending into the tanks are outlet pipes 4 equipped at their outer ends with fittings 5 to which flexible tubes I are secured.

' 35 'Ihe inner ends of the pipes l are spaced a con`- siderable distance from ,the bottoms of the tanks so that any sediment'accumulatedin the tanks will not be disturbed or agitated by the use of the device. Filling pipes I are connected to the pipes 40 4 whereby the cleaning solution or fluid may be directed into the tanks. 'I'he lling pipes are normally closed by removable caps l and also connected to the nlling pipes are pressure gages 9 whereby the operator may at any time deter-1 mine the pressure within the tanks. The flexible tubes 6 have interposed therein control valves Il having pressure gages II. 'I'he flexible tubes are adapted to be connected in any suitable way-to the intake and outlet'necks or pipes of a motor vehicle radiator I2. l

Pressure pipes I3 are connected to the tanks 'adjacent the -latters upper end and have interposed therein control valves II and carry at their outer ends air release valves I5 of any conventional. type placing the outer ends of the pressure pipes I3 at all times in communication with v the atmosphere. 1

A main air pressure supply pipe is indicated by the character v'I8 and is provided with a control valve II. Branch pipes I8 are connected to the 5 air pressure pipe I6 and to pipes I9, thelatter being connected tothe fittings I and to the pres-AI sure pipes Il. The pipes Il above the points of connection -of the' pipes Itherewith, that is, above the T-connections therebetween are pro- 10 vided with the cutoi valves I8.

'I'he operation of` this invention is as follows:

Cleaning fluid is placed inthe tanks A and B with the tank A containing more fluid than thetank B as indicated by the dotted lines in the 15 drawing. A radiator is then connected to the tubes 6. The valve I'I is opened, also the valves Il' and 28 to the tank A, placing'the liquid in tank A under air pressure. 'I'he valves Il of the tubes I lare open and the valve I4 of tank B is'zo open. The cleaning solution fromtank A passes outwardly through the pipe l of said tank A,

mixing with air under pressure at the fitting' 6, the air and solution mixing and passing on intoA the radiator under a desired pressure and pass- 26 ing from said radiator to the ytank B, carrying therewith any foreign matter which* may be in the radiator, and depositing such foreign matter in the tank B. After this operation, the flow of iluid may' be reversed, that is fluid from the tank 30 B may be passed through the radiator to the tank A by opening the valves 20 and I 8' of the `tank B and closing the valves 20 and I8 of the tank A and opening the valve I4 of the tank A and closing the valve Il of the tank B. As the 35 foreign matter enters the tanks it naturally gravitates to the bottom vof the tanks and after the use of this device over a period of time said tanks may be emptied of the foreign matter along with Vthe `cleaning solution and in many ,instances the 40 cleaning fluid may be rectified and used over again in this device. After the cleaning of the radiator of foreign matter and if it is desired to test the radiator for leaks the valves 2U are closed and the valves I8 and I1 are opened placing the 45 radiator under air pressure so that should a defect be in the radiator of the nature which would permit escape of air, the. operator may readily locate such defect by the hissing sound produced by escaping air.

Having described the invention, I claim:

A radiator cleaner and leak tester comprising a pair of closed tanks adapted to contain cleaning fluid, outlet pipes connected tosaid tanks, fittings connected to said outlet pipes, exible tubes concleaning uid in either one of said tanks may be passed therefrom through the radiator to the other tank, means whereby either of said tanks may be vented, and combined pressure indicating means and tank lling means connected to each 5 of said pipes.
